Be it known that L ALnnirr DonsoN, a subject of the lling of (.lreatllritain, and resid` ing at 507 Notre Dame Street, St. Lambert, in the. Province ofi Quebec, in theDominion of Canada, have invented new and useful in a warm condition during` cold weather and thoroughly sterilized.` y i The objects of the invention are particularly in railway passenger. car construction, to so arrange the toilet conveniences as to have a closed container which will protect the roadway when entering* the precincts of ylaine cities or towns and thereby not affect the' comfort of the passengers to insure clean and sanitary comlitions,thus improv-A in health conditions where so many people congregate and use common conveniences; to facilitate the operation ofthe parts notwith` stan'clinna climatic conditions; and ,generally to complete the installations in railway cars for toilet conveniences. j

, Figure 9fis a. plan view 'of illustrated in Figure S. f v Figure 10 is a detailof the' locking` and flainge.` y i Lilie numerals of reference indicate responding' parts in each figure.

Referring' to! they dra-wings, the vnumeral 1i indicates a bowl or container which is operating` means ring CO l'- preferably made in hopper shape flaring up@ wardly from the lower discharge opening' 2, particularly in one direction 3, to make said discharge opening 2 eccentric in relation to the upper end' 4 of they howl.

At the upper end, the wall of the howl 1 is flanged at 5 land the plate y(l having;` the flange 7 projecting` frointhe under side and the inlet passage 8, is mounted on the flange 5 of the bowll.

f The ring` 9 forms with flange thereof, said ring;` heine' formed with the "flange section 10 secured by the screws 11l to the rplate 6, and the channel curved section 12, which extends into proximity with the llower end of the flange 7 leaving, suflicient opening' therebetween for the escape of the water in the direction ofthe howl wall.

vj The howl 1 towards the lower end thereof is formed with the slott d flange 13, while over the passage S the ordinary toilet howl 14 is securely mounted.

The locking 'ring` 15 Aformed with slots 1G and threaded barrel portion 17 issecured on the bowl 1I over the flange 13 and extends below said flange.

The steam jacket 18' is formed to encircle the lower end of thefbowl 1 between the flange 18 and the lower end of the bowl.

The inner wall 19 of thesteam jacket 18A follows the converging,` sha-pe of ythe howl wall and is so formed: as to leave the hotk air space 20 completely encircling. the wall of the bowl 1, said inner wall projecting` downwardly to form with the `said bowl wall, the annular packing` slot 21 in which the lead ring` 221 is inserted.

v"lhevertical wall Q3 of the steam jacket is threaded at its upper end andV screwed'into f the locking;` ring 15 drawing' said .locking rin'gtiglitly down to the 'flange 13 and itself tigl fly upto the flange 13, The lower wall 24e of the steam jacket 18 extends alonnand forms the bottom of the steam inlet passage 25, which communicates 7 the water j passage around the howl 1 at the upper end with the said steam jacket 1S and has a lower port 2G communicating with the slide chamber 27.

rlhe end wall 2S of the slide chamber is rigidly secured to the bottom of the steam jacket 1S and side walls 29 extend from said end wall 2S and are formed with the ledges 30.

The slide chamber or steam passage 2T is formed around the bowl outlet 31 and eX- tends therefrom.

The hollow slide 32 closes the outlet 8l and forms in itself a steam chamber 33 coinmunicat-ing with said passage 27, the bottoni ribs or ledges 34 being wedge shaped to coact with the ribs or ledges 30 in moving the slide 32 upwardly against the packing ring 22.

The rib or bead projects upwardly from the top surface of the slide and borders the fiat inner surface on three sides and the end portion of the top is thickened to forni a raised table 36 for the valves to slide on. The diamond shaped boss 37 projects upwardly from said table 3G midway between the sides and is intended to operate the valves on the movement of the slide` The lugs 3S project from the end of the slide 82 and the connecting rod 39 is pivotally secured at one end to said lugs 38 and at the other end carries the rack 40.

The valves 4l and 42 are slidably secured in a recess of the wall 24 of the steam jacket 18 and move on the surface of table 36 to bring the ports in the valves in register with the ports 4G in the wall 24.

rllhe valves 4l and 42 have the inner tapered ends 43, engaged by the boss 37 in sliding the valves outwardly, and the outer tapered ends 44 engaged b y the corner bosses 47 or the corner bosses 4S of the slide 32 in sliding the valves inwardly.

lhile the slide remains fully open there will be no steam fed for sterilizing purposes on to the inside :tace of the slide though during the travel of said slide the said inner face is thoroughly sterilized. But the return of the slide to its closed position means the reopening of the valves by the parting boss 37 and a fresh sterilization, however the opposite corner bosses 48 again move the valves 4l and 42 to their closed positions and cnt oli' the steam from the tace of the slide 32, thus in both sliding ontwardly and inwardly the bottoni of the bowl is well cleaned.

The rack frame 40 is formed with the longitudinal shaft slot 49 and the rack 5 mounted on one side of the frame adjacent to said slot.

The vertical shaft 5l extends through the shaft slot 49 and carries said rack frame at its lower end, said shaft 51 being` secured therein by the washer 52 and nut 53.

The pinion 54 is mounted on the shaft 5l messes and coacts with the rack in sliding the slide 32, the said shaft 5l being operated at its upper end within the car by the crank handle 55.

The crank handle 55 is situated Vin the porters locker 5G and also the controlling valve 5T for the water tlowing to the flushin;` channel.`

The valve 57 is operated by the arm mounted on the stein of the valve and connected to the lng 59 on the door Gt) by the iod (3l, therefore when the door GO is opened the valve 57 is also opened and the flushing j. L A A p oi die bowl i occurs simultaneously with the opening of the door.

The opening` of the door G0 also relieves the shaft handle from engagement with the spring 62, which extends into the locker 56 in two sections, one section to hold the shaft handle in the closed position of the slide 82 and the other section to hold the shaft handle tightly in the opening position of the slide 32, that there shall be no rattling'.

rllie ovcrtlow (33 is situated at one side the top plate of the bowl l through the toilet room of the Car and through the root'.

The flushing channel in the ring 9 is connected to the water reservoir through the valve 57 hy the pipe G7 and the cover plate is thickened at the entrance to this pipe and the wall of the channel slightly dropped and formed in the interior with an upwardlyv projectingv parting rib G8. which naturally divides the water entering and sends it in the two directions.

The lower structure is preferably enclosed in a wooden framework G9. which also encloses the heated chamber TO having a liningl of insulated paper 7l. i

rllhc inlet port 73 to the steam jacket '1S is connected through the passage 25 with the steam pipe 72 from the train line pipe` thereby maintaining` a constant suppli.7 of steam around the lower end of thc howl.

The operation of this invention has been mostly described in setting' forth the details of construction as it is the, porters work to open his locker and pull the slide when the train has cleared the precincts of the city and is well out in the Vopen coun- Tliere will be no ditiieiilty in doing;` this in the most severe weather. and there will he no accumulation of waste notwithstanding climatic conditions. because the lower end of the bowl is always maintained at a nice comfortable temperature hiv the steam jacket snri'oiiinlingl the same and the slide is heated in the interior so that there. cannot he a collection of ice therearound. furthermore the whole surroundings are conllt) llS

stantly treated with'liot steam and hot kair, and the inside facer of the slide well sterilized as explained liereinbefore.
